The antibacterial action of ginger?

According to historical records, the use of ginger dates back over 3,500 years, although it is likely to be even older. This plant, native to Southeast Asia, was introduced to Mediterranean Europe during antiquity through maritime trade before spreading to the rest of the continent. Initially used as an aromatic and medicinal plant, the ginger is now considered a staple in cosmetics.

Among its most appreciated properties, is its antibacterial action. However, it should be noted that, to fully benefit from this property, it is strongly recommended to opt for a ginger essential oil, rich in bioactive terpenes. Indeed, this essential oil contains α-pinene, a molecule with bacteriostatic properties against Gram-positive bacteria. Without directly killing these bacterial populations, α-pinene is capable of inhibiting their multiplication.

Another intriguing terpene found in ginger essential oil is limonene. Renowned for its tangy fragrance, this molecule is also recognised for its antibacterial action. Indeed, limonene acts on certain Gram-positive bacteria such asEscherichia coli, a bacterium present in the human digestive tract, and prevents their proliferation. In practical terms, limonene causes the rupture of the bacterial membrane, which compromises the cellular integrity of the bacterium.

Antiseptic in nature, ginger extract is frequently used in the formulation of skincare products intended for skin prone to blemishes or acne. Indeed, the antibacterial properties of this ingredient are particularly suitable for combating acne, which can be caused by the proliferation of the Gram-positive bacteria Cutibacterium acnes.

To reduce blemishes, we recommend applying a few drops of ginger essential oil mixed with a non-comedogenic vegetable oil locally. A dilution between 1 and 2% is recommended. You can also apply the mixture preventively over the entire area of your body prone to spots.

If you suffer from acne, ginger cannot replace the treatment prescribed by a dermatologist, it can simply complement it.

Ginger can also be used to disinfect minor wounds. In addition to its antibacterial properties, ginger has anti-inflammatory properties that allow it to soothe the skin, relieve pain, and promote healing. This ingredient can thus be considered a natural dressing, which can be used in cases of small cuts or sunburn, for example.
